Because X and Y are awesome games (and because I wanted to try writing something new), here's an alternate take on how the events at Frost Cavern unfolded. Based on the in-game universe of X and Y (Serena as the MC and Calem as the rival).
Uploaded a bit early because the date was really cool and I wanted it to be on my story. :3 All other chapters will be longer than this little prologue (there should be three or four, not counting this one). I'm hoping Kalosshipping is the correct term for Calem x Serena, because that is what this is.
…
The wind howled as globs of snow whipped through the rapidly darkening sky. Frost Cavern was aptly named, and few pokemon, let alone people, would ever dare to venture near it when it was in this foul of a mood. Exceptions were only made when the weather decided to take its victims by surprise.
Serena was one such victim.
The young girl's breaths came in quick gasps as she stumbled blindly through the blizzard. Her long honey-brown hair was beginning to freeze together, and her violent shivers only served to impede her movement. Her arms wrapped around her soaked body, trying desperately to retain what little heat she had left. Serena tried to turn back to the mouth of the cave to see how much progress she'd made back to civilization, and even through the bulleting snow could see that she'd barely made it ten steps. She forced her muscles to take another: eleven steps down on a twenty minute walk.
She knew she wouldn't make it. A wave of dizziness hit her as she realized how much danger she was in, and she collapsed in a heap onto the wet ground. Her arm trembled as she tried to make her numb fingers wrap around the clasp to her pink purse, and she gritted her teeth in concentration. Her one remaining pokemon was all that lay between her and a frosty death.
After several seconds of fumbling, Serena managed to open her bag. The contents spilled onto the ground from her shaky grasp, including four precious pokeballs.
"J-J-Jolteon!" Serena croaked, reaching desperately toward the quick ball that housed the creature. "J-Jolteon, p-p-plea…"
There was a flash of light, and the spiky yellow dog appeared. She squinted against the wind and shook herself lightly, but then noticed the state of her trainer. "Jolt!" she called, crouching down low to Serena with worried eyes. "Jolt! Jolt!"
"Run…" Serena said, her cracking tone barely above a whisper. "Jolteon, run a-a-and… a-and…"
"Jolt! Jolteon!"
"G-g-ge… help…"
There was a loud crack of electricity as the jolteon fired a terrified thunderbolt to the sky. Serena saw the flash right before her eyes fell shut.
